Module Name:

    ctlkacct.c

Abstract:

    Local Security Authority Subsystem - Short CT for Win 32 LookupAccountName/Sid

    This is a small test that simply calls the Win 32 LookupAccountName/Sid
    API once.

Usage:

    ctlkacct \\ServerName AccountName

Building Instructions:

    nmake UMTEST=ctlkacc UMTYPE=console
